Hi berkeman, If either input is 1, then current will flow through the diode and there will be a voltage drop across the resistor. Ok I get that... but I don't understand the link between that and the output being 1 If both input are zero then no current will flow through the diodes. I...

Hello guys, I'm not getting the output of the diode logic circuits: http://upload.wikimedia.org/wikipedia/commons/1/1f/Diode-OR2.png If both inputs are 1, then there is current across the diodes then the output is 1, but shouldn't it drop because of the resistor R? If both inputs are...

Ok then, Thanks!

I know it may be simple, but I'm still confuse, -1 divided by 3 has a remainder of -1 2 divided by 3 has a remainder of 2 So I don't get how they have the same remainder

Homework Statement Find the determinant of: |1 1| |2 1| The field is Z3. Homework Equations The field is Z3, that is, to multiply two numbers, you first multiply then take the remainder of the division by 3. The Attempt at a Solution I tried: ( 1 x 1 ) - ( 1 x 2 ) 1 x 1 will...

Got it! Thanks

Hey DH thanks for helping, but I still don't get it, I mean... I need to know what's the next step of (NOT A)(NOT B)(C) + B. In your answer, you are saying that I need to expand the right side... but in a real exercise, I wouldn't know what the right side would look like

Homework Statement I'm studying function simplification in boolean algebra, and I didnt understand the following step: (NOT A)(NOT B)(C) + B = (NOT A)(C) + B What happened to the NOT B? Homework Equations The Attempt at a Solution
